revert to revision in svn

Question

Is there a way to revert to a certain revision while keeping the changes in comments. for example :-

Revision 33:-

public class A{
    private aa;
    private bb;
    private cc;
}

Revision 34:-

public class A{
    private aa;
    private bb;
    private cc;
    private dd;
}

and then there are many other revisions. Now if i revert changes from revision 34, I want the my local copy to look like this:-

Revision 120:-

public class A{
     private aa;
     private bb;
     /* changes from revision 34 reverted by XXXX on YYYY
      * Following changes were reverted:-
      *private cc;
     */
}

Is is possible to do this?

This sounds very close to the blame command:

Show author and revision information inline for the specified files [...].

It will show, for every line of the file, the revision it was added/modified and who the author of that revision is. Example:

>svn blame http://svn.apache.org/repos/asf/subversion/trunk/README

If you use TortoiseSVN, you can see the commit message for each line via a tooltip:

tortoiseproc /command:blame /path:http://svn.apache.org/repos/asf/subversion/trunk/README

Note: A limitation of this command is that it will not show you lines that were removed; only lines that are visible in the revision you are blaming will be shown.
